Hi all, Just repeating the question about the draft<https://datatracker.ietf.org/doc/html/draft-dong-spring-srv6-inter-layer-programming-08> I've asked at he mike at the SPRING WG session today.
* Suppose that there is an underlay link between a pair of IP nodes that is not "visible in he L3 topology". To me this means that there no P-capable (logical) interfaces associated with the endpoints of this underlay link * Suppose further that one of these nodes (the upstream one) allocates and advertises an SID with End.XU behavior for this underlay link * The upstream node receives an IPv6 packets with the tops SRv6 SID on it being the End.XU. It strips this SID (this the common behavior of all End-like SIDs) and send the resulting IPv6 packet across the link to the downstream node/\. Now the question: How should the downstream node process the received packet if its local endpoint of the undelay link s not associated with an IP-capable logical interface? If the endpoints of the underlay ink are associated with L3 interfaces in both nodes, the link becomes visible in L3 topology, and a regular End.X SID can be allocated and advertised for it. Hopefully this clarifies my question.
